Founded by religious fundamentalists, BF seek a new "holy war" on the streets of Britain.

Fransen has been arrested multiple times.

LONDON — Donald Trump today repeatedly retweeted a series of Islamophobic tweets from Jayda Fransen, the notorious deputy leader of the far right group Britain First.

Trump retweeted a series of violent videos tweeted by Fransen, who was recently arrested and charged for comments she made at a speech in Belfast.

Who are Britain First?

Their Facebook page has almost half a million likes, with up to two million people a day engaging with their 'patriotic' pictures of soldiers, little children and Union Jacks.

However, behind the social media facade lies a small group of religious fundamentalists intent on starting a 'holy war' on the streets of Britain.

One of the founders of the group was Jim Dowson, a hardline evangelical anti-abortion activist with close ties to Loyalist paramilitary groups in Northern Ireland.

The former BNP fundraiser was arrested for organising several illegal parades in Northern Ireland which culminated in a series of violent clashes on the streets of Belfast.

In an interview with Channel Four News, Dowson admitted to pursuing a "holy war" on the streets of Britain:

"One thing I agree with Mr Choudry on, there is such a concept as a just war, a holy war. He calls it Jihad. We call it a crusade," he told Paraic O'Brien.

"Without any shadow of a doubt, this is a holy war."

The group's leader is Paul Golding, a former BNP councillor and the man behind Britain First's attempts to build a uniformed "Christian defence force" in the UK.

Driving in military Land Rovers and wearing paramilitary-style uniforms, the group have staged a series of mosque invasions across the country and almost fomented a riot on Brick Lane in London.

In 2014 they held a flag ceremony in which masked activists were handed battle standards before being divided into battalions and companies.

Members have also been filmed training in unarmed combat. Former members of the armed services are actively courted by the group.

Golding has been held a total of four times by anti-terror police.

It's deputy leader Jayda Fransen, who was retweeted by Trump today, is now the most high-profile member of the group.

In November Fransen was convicted of religiously aggravated harassment for shouting at a Muslim woman during a so-called "Christian patrol" of the town of Luton.

Fransen is also awaiting trial for inciting religious hatred and has also been charged in relation to a speech she made in Northern Ireland.
